Description

Technical Field

[0001] This utility model relates to the field of refrigeration system technology, specifically to a novel vehicle-mounted refrigeration system. Background Technology

[0002] Most car refrigerators on the market use independent compressor refrigeration systems or semiconductor refrigeration systems. However, both of these refrigeration systems are independently installed in the car and require a large amount of space inside the vehicle's instrument panel.

[0003] Patent document CN201010259104.6 discloses a dual-temperature control vehicle refrigerator refrigeration system, providing a dual-temperature control vehicle refrigerator refrigeration system with good performance and arbitrary control from freezing to refrigeration. This invention consists of at least one compressor refrigeration system and two evaporator systems. The compressor refrigeration system is controlled by two relays, each relay being controlled by a solenoid valve, which is controlled by a temperature sensor. The cold source for each of the cooled compartments is provided by its respective evaporator, and each solenoid valve controls one evaporator system.

[0004] However, the aforementioned compressor-based refrigerator refrigeration system not only requires the placement of compressor modules, cooling modules including radiator fans and filter modules within the sub-instrument panel, occupying a significant amount of space, but also suffers from reduced user experience due to refrigerator fan noise and heat dissipation, and overall high cost. Therefore, there is an urgent need to develop a new type of in-vehicle refrigerator that no longer uses an independent compressor or semiconductor-based refrigeration system. Instead, it should be a refrigeration system that is integrated and matched with the vehicle's thermal management system, thereby reducing costs and increasing user comfort. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0019] Example 1, such as Figure 1-3As shown, this novel vehicle-mounted refrigeration system mainly consists of a vehicle-mounted air conditioning compressor 1, a vehicle-mounted condenser 2, a dryer filter 3, a vehicle-mounted refrigerator refrigeration system 4, a vehicle-mounted air conditioning refrigeration system 5, a three-way flange interface 6, and a battery refrigeration system 7. All components are sequentially connected via pipelines to form a complete refrigeration cycle system.

[0020] The vehicle air conditioning compressor 1, acting as the power source for the refrigeration system, compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant is then transported through pipelines to the vehicle condenser 2, which is installed at the front of the vehicle. Utilizing the oncoming wind or fan ventilation, the heat of the high-temperature, high-pressure gaseous refrigerant is dissipated into the outside air, causing it to cool and condense into a medium-temperature, high-pressure liquid refrigerant. This medium-temperature, high-pressure liquid refrigerant then flows into the dryer filter 3, which filters out moisture and impurities from the refrigerant, ensuring its purity and preventing moisture from freezing and clogging the pipes.

[0021] like Figure 1-2 As shown, The two-way flange interface 40 serves as the connecting component between the vehicle refrigerator refrigeration system 4 and the original vehicle air conditioning basic refrigeration cycle. The liquid inlet pipe 401 is connected to the output port of the dryer filter 3, and the liquid outlet pipe 402 is connected to the subsequent turbocharger 8 and gas-liquid separator 9.

[0022] The first solenoid valve 41 is installed between the liquid inlet pipe 401 and the capillary tube 42, and is connected to the vehicle's control system through a control circuit. When the vehicle refrigerator needs to be cooled, the control system sends a signal to open the first solenoid valve 41, and the refrigerant enters the first solenoid valve 41 from the dryer filter 3 through the liquid inlet pipe 401, and then flows into the capillary tube 42.

[0023] The capillary tube 42 serves to throttle and reduce pressure. Its inner diameter is small. After the refrigerant passes through the capillary tube 42, the pressure and temperature decrease, and then it flows into the refrigerator evaporator 43.

[0024] The refrigerator evaporator 43 is installed inside the vehicle refrigerator, where refrigerant evaporates and absorbs heat to achieve a cooling effect. The surface of the evaporator should have good thermal conductivity to improve cooling efficiency. The output port of the refrigerator evaporator 43 is connected to a first check valve 44 to prevent refrigerant backflow.

[0025] The first check valve 44 ensures that refrigerant flows from the refrigerator evaporator 43 to the low-pressure inlet 81 of the booster 8. When the refrigerant pressure reaches a certain value, the check valve opens, and the refrigerant flows out through the liquid outlet pipe 402.

[0026] The vehicle refrigerator refrigeration system 4 also includes a cold storage and evaporation assembly 45 and a fan 46, which enhance the refrigeration efficiency of the vehicle refrigerator refrigeration system 4.

[0027] like Figure 2 As shown, the booster 8 includes a low-pressure inlet 81, a high-pressure inlet 82, and a mixing outlet 83. The upper end of the first flow pipe 61 is connected to the liquid outlet pipe 402 of the two-way flange interface 40, and the lower end of the first flow pipe 61 is connected to the low-pressure inlet 81. The high-pressure inlet 82 is connected to the outlet of the first check valve 44. The booster pressurizes the recovered refrigerant through its internal mechanical structure, and then inputs the pressurized refrigerant into the gas-liquid separator 9 through the mixing outlet 83.

[0028] The gas-liquid separator 9 is used to separate the gaseous and liquid components in the refrigerant. The mixing outlet 83 is connected to the inlet of the gas-liquid separator 9. After the refrigerant enters the gas-liquid separator 9, the gas rises and the liquid sinks. The outlet of the gas-liquid separator 9 is connected to the inlet of the vehicle air conditioning compressor 1 through a pipeline, so that the separated liquid refrigerant is sent back to the compressor, realizing the recycling of the refrigerant.

[0029] In the turbocharger 8, refrigerant from the high-pressure inlet 82 and the low-pressure inlet 81 are mixed, and then flow out from the mixing outlet 83 into the gas-liquid separator 9. The function of the gas-liquid separator 9 is to separate the liquid and gas in the mixed refrigerant, ensuring that the refrigerant entering the vehicle air conditioning compressor 1 is gaseous, and preventing liquid refrigerant from entering the compressor and causing damage. The gaseous refrigerant separated by the gas-liquid separator 9 flows out from its outlet and is transported through pipelines to the inlet of the vehicle air conditioning compressor 1 to complete the vehicle refrigerator refrigeration cycle.

[0030] like Figures 2-3 As shown, the two-way flange interface 40 serves as the connecting component between the vehicle refrigerator refrigeration system 4 and the original vehicle air conditioning basic refrigeration cycle. The liquid inlet pipe 401 is connected to the output port of the dryer filter 3, and the liquid outlet pipe 402 is connected to the subsequent turbocharger 8 and gas-liquid separator 9.

[0031] The first solenoid valve 41 is installed between the liquid inlet pipe 401 and the capillary tube 42, and is connected to the vehicle's control system through a control circuit. When the vehicle refrigerator needs to be cooled, the control system sends a signal to open the first solenoid valve 41, and the refrigerant enters the first solenoid valve 41 from the dryer filter 3 through the liquid inlet pipe 401, and then flows into the capillary tube 42.

[0032] The capillary tube 42 serves to throttle and reduce pressure. Its inner diameter is small. After the refrigerant passes through the capillary tube 42, the pressure and temperature decrease, and then it flows into the refrigerator evaporator 43.

[0033] The refrigerator evaporator 43 is installed inside the vehicle refrigerator, where refrigerant evaporates and absorbs heat to achieve a cooling effect. The surface of the evaporator should have good thermal conductivity to improve cooling efficiency. The output port of the refrigerator evaporator 43 is connected to a first check valve 44 to prevent refrigerant backflow.

[0034] The first check valve 44 ensures that refrigerant flows from the refrigerator evaporator 43 to the low-pressure inlet 81 of the booster 8. When the refrigerant pressure reaches a certain value, the check valve opens, and the refrigerant flows out through the liquid outlet pipe 402.

[0035] The vehicle refrigerator refrigeration system 4 also includes a cold storage and evaporation assembly 45 and a fan 46, which increase the flow rate of cooling gas and enhance the refrigeration efficiency of the vehicle refrigerator refrigeration system 4.

[0036] The booster 8 includes a low-pressure inlet 81, a high-pressure inlet 82, and a mixing outlet 83. The upper end of the first flow pipe 61 is connected to the liquid outlet pipe 402 of the two-way flange interface 40, and the lower end of the first flow pipe 61 is connected to the low-pressure inlet 81. The high-pressure inlet 82 is connected to the outlet of the first check valve 44. The booster pressurizes the recovered refrigerant through its internal mechanical structure, and then inputs the pressurized refrigerant into the gas-liquid separator 9 through the mixing outlet 83.

[0037] The gas-liquid separator 9 is used to separate the gaseous and liquid components in the refrigerant. The mixing outlet 83 is connected to the inlet of the gas-liquid separator 9. After the refrigerant enters the gas-liquid separator 9, the gas rises and the liquid sinks. The outlet of the gas-liquid separator 9 is connected to the inlet of the vehicle air conditioning compressor 1 through a pipeline, so that the separated liquid refrigerant is sent back to the compressor, realizing the recycling of the refrigerant.

[0038] The three-way flange interface 6 includes a first flow pipe 61, a second flow pipe 62, and a third flow pipe 63. The first flow pipe 61 is connected to the liquid outlet pipe 402 of the two-way flange interface 40. The upper end of the second flow pipe 62 is connected to the output ports of the air conditioning evaporator 53 and the battery pack evaporator 72, realizing the collection and recovery of refrigerant in the vehicle air conditioning refrigeration system 5 and the battery pack evaporation system 7. A second check valve 64 is provided on the second flow pipe 62, which is then connected to the high-pressure inlet 82 of the turbocharger 8, allowing refrigerant to enter the turbocharger 8 through the second check valve 64. The inlet pipe of the third flow pipe 63 is connected to the outlet of the gas-liquid separator 9, and the outlet pipe of the third flow pipe 63 is connected to the inlet of the vehicle air conditioning compressor 1, completing the transport of refrigerant from the gas-liquid separator 9 to the compressor, forming a complete refrigeration cycle.

[0039] In the vehicle air conditioning refrigeration system 5, the inlet of the second solenoid valve 51 is connected to the outlet of the dryer filter 3, and is connected to the vehicle's air conditioning control system through a control circuit. When the vehicle air conditioning is turned on, the control system sends a signal to open the second solenoid valve 51, allowing refrigerant to flow from the dryer filter 3 into the second solenoid valve 51. The two ends of the thermostatic expansion valve 52 are connected to the second solenoid valve 51 and the air conditioning evaporator 53, respectively. The refrigerant flow rate is automatically adjusted according to the superheat of the refrigerant at the evaporator outlet to achieve throttling control. After the refrigerant passes through the thermostatic expansion valve 52 and its pressure is reduced, it enters the air conditioning evaporator 53. The air conditioning evaporator 53 is installed inside the vehicle's driver's compartment, where the refrigerant evaporates and absorbs heat, lowering the temperature inside the driver's compartment. The air conditioning evaporator 53 is connected to the vehicle's ventilation system through a duct, blowing cold air into the driver's compartment to achieve a cooling effect.

[0040] The refrigerant passing through the air conditioner evaporator 53 is connected to the second flow pipe 62 through a pipe, then flows through the second check valve 64, into the high-pressure inlet 82 of the booster 8, and then enters the gas-liquid separator 9, returning to the inlet of the compressor 1.

[0041] Example 2: Existing vehicle models also include a large number of electric vehicles. During the use of electric vehicles, their batteries will generate a lot of heat during discharge. If they are not cooled, the battery stack may overheat and burn. Therefore, the cooling system also includes a battery cooling system 7.

[0042] like Figure 3 As shown, the output port of the dryer filter 3 is also connected to the input port of the electromagnetic expansion valve 71 in the battery refrigeration system 7 via a pipeline. The electromagnetic expansion valve 71 can control the refrigerant flow rate according to the temperature requirements of the battery pack. When the battery pack temperature is too high and cooling is required, the electromagnetic expansion valve 71 opens, and medium-temperature, high-pressure liquid refrigerant enters the electromagnetic expansion valve 71 and flows out from its output port into the battery pack evaporator 72. The battery pack evaporator 72 absorbs the heat from the battery pack, causing the refrigerant to evaporate into low-temperature, low-pressure gaseous refrigerant, which then flows out from the output port of the battery pack evaporator 72 and is transported through a pipeline to the second flow pipe 62 of the three-way flange interface 6, returning the evaporated refrigerant to the system for circulation.

[0043] The vehicle-mounted refrigeration system of this invention can switch between multiple working modes according to different refrigeration needs by controlling the state of the first solenoid valve 41, the second solenoid valve 51, the solenoid expansion valve 71 and the three-way flange interface 6.

[0044] System working principle: Independent vehicle refrigerator cooling mode: Open the first solenoid valve 41 and close the second solenoid valve 51 and the solenoid expansion valve 71. The refrigerant flows out from the dryer filter 3, passes through the first solenoid valve 41 and the capillary tube 42 into the refrigerator evaporator 43 to cool the vehicle refrigerator, and then passes through the first check valve 44, the booster 8 and the gas-liquid separator 9 back to the vehicle air conditioning compressor 1.

[0045] Independent vehicle air conditioning cooling mode: Open the second solenoid valve 51 and close the first solenoid valve 41 and the solenoid expansion valve 71. The refrigerant flows out from the dryer filter 3, passes through the second solenoid valve 51 and the thermal expansion valve 52, enters the air conditioning evaporator 53 to cool the vehicle air conditioning, and then returns to the vehicle air conditioning compressor 1 through the three-way flange interface 6.

[0046] Battery-only cooling mode: Open the electromagnetic expansion valve 71 and close the first electromagnetic valve 41 and the second electromagnetic valve 51. Refrigerant flows out from the dryer filter 3, passes through the electromagnetic expansion valve 71 and enters the battery pack evaporator 72 to cool the battery pack, and then returns to the vehicle air conditioning compressor 1 through the three-way flange interface 6.

[0047] Multiple cooling modes can work simultaneously: According to actual needs, multiple solenoid valves can be opened at the same time, so that the refrigerant flows to different evaporators at the same time, achieving simultaneous cooling of the vehicle refrigerator, vehicle air conditioner and battery pack.

[0048] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
